Patented Oct. 8, 1 929 CLAUDIUS NIELSEN, OF DETROIT, MICHIGAN ICE CASINGFOR REFRIGERATORS Application filed June 10,

My invention relates to a new and useful improvement in a casing for thereception of ice in refrigerators, and has for its object the provisionof a device of this class which will effect an economy in the use of icein refrigerators without materially lessening the refrigeratingefficiency of the refrigerator.

Another object of the invention is the provision of a device of thisclass which will be simple in structure, economical of manufacture andhighly efficient in use.

Another object of the invention is the provision of a casin ofthisclas's of a'formation to effect the air circulation in therefrigerator in such a manner as to maintain the refrigerator atsubstantially its normal refrigerating etiiciency, while at the sametime retarding the melting of the ice used therewith.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of partshereinafter described and claimed.

. 1 The invention will be best understood by a reference to theaccompanying drawings which form a part of this specification and inwhich.

Fig. 1 is a fragmentary front elevational view of the ice compartment ofa refrigerator showing the invention applied.

Fig. 2 is a fragmentary sectional view taken on substantially line 2-2of Fig. 1.

Fig. 3 is a perspective view of the invention in a form for mounting inthe compartment of a refrigerator.

Fig. 4 is a sectional view similar to Fig. 2 of a modified form showinthe invention permanently built into a refrigerator.

The invention is adapted either for mounting in a refri erator or forbuilding perma-- 4o nently in a refrigerator and in the preferred formsI have shown a refrigerator 7 with the ice compartment 8 and a door 9for the compartment. The invention comprises a casing which ispreferably made from metal and 45 embodies a side wall 10, a rear wall11 and a side wall 12. The upper edges of the side walls 10 and 12 andthe rear wall 11 are provided with the inwardly projecting flanges 10',12 and 11 respectively, to which is suitably secured, by soldering,welding, or in any 1926. Serial No. 114,886.

other manner, a top 13. The side walls and rear walls are provided withventilating openings'14 formed by punching the shield tongues 15therefrom, these tongues serving as shields for preventing access to theopenings 14 formed above. mounted on the wall 12 and serves as a closurefor the forward end of the casing. Swingably mounted on the top 13 is aflap comprising the portions 17 and 18, the flap 17 being adapted, asshown in Fig. 3, for folding downwardly so as to close the crevicebetween the upper edge of the door 16 and the under surface of the top13. A similar flap comprising the portions 22 and 23 is mounted on theside wall lOfor closing the crevice between the edge of-the wall 10 andthe inner surface of the door 16.

As shown in Fig. 2 the lower edge of the opening 19 of the compartmentis positioned A door 16 is hingedlyabove'the base 20 of the ice chamberand it will be noted in Fig. 3 that the walls 10 and 12 project belowthe lower edge of the door 16, so that when the casing is mounted in theice chamber'orcompartment 8 the door 16 may be readily opened. 'When thedevice is mounted in the ice chamber or compartment 8 in the maner shownin Fig. 1 and Fig. 2 the ice 21 is positioned in the casing. and it willbe noted that the upper surface of the ice 21 is spaced from the undersurface of the top 13, this bcing' preferable for most efficientresults.

Tests with recording thermometers have proven that the use of the devicedescrilxd results in considerable saving in ice necessary for use in arefrigerator without lessening the efliciency of therefrigerator for.refrigerating puposes, the temperature beingsubstantially the same in arefrigerator in which applicants device is used and in a refrigerator ofthe same kind in which applicants device is not used. But in therefrigerator in which applicants device is used a considerable saving ofice is effected as the ice does not melt so rapidly. It is believed thatthe-device renders the refrigerator most efficient because of cooling insubstantially the same degree with a less meltingof ice, and it isthought that this increase in efficiency results from the structedsubstantially as described for the preferred form,

the shields 15. The device is shown as mounted on the top24 of therefrigerator.

It will be noted that the side and rear walls as Well as the top wall ofthe deviceare in spaced relation tovthe inner surface of the compartmentor chamber 8 and it is believed that greater efficiency results when thedevice is so positioned.

While I have illustrated and described the preferred form of structure,I do not wish to limit myself to the precise form of structure shown,but desire to avail myself of such variations and modifications as maycome within the scope of the appended claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. An ice casing of the class describedcomprising a top wall, a rear wall and side walls, said rearwall andsaid side walls having vent openings formed therein; and meansassociated with each of said openings for deflecting downwardly airpassing therethrough from the inside thereof.

2. A.device of the class described comprising metallic side and rearwalls adapted for mounting in the chamber of a refrigerator, a top wallcarried by said side and rear walls, said walls being in spaced relationto the inner surface of said chamber, said side and rear walls havingvent openings formed therein for permitting the flow of air outwardlyfrom the interior of said casing; defleeting members mounted on theouter surface of said casing for deflecting downwardly air passingoutwardly from said casing through said openings; a closure mounted onsaid side walls; means for closing the crevice between the edges of saidclosure, and said top wall and said side wall.

In testimony whereof I have signed the foregoing.
